Setting eth0 address on Xavier

Hi!
I am trying to change an IP address for eth0 but cannot ping board after it

  1. I am looking at
    /etc/systemd/network/99-nv_eth0_default.network

[Match]
Name=eth0

[Network]
DHCP=ipv4

I am trying to change from

DHCP=ipv4
to
Address=192.168.7.142/24
But after this i cannot ping 92.168.7.142 address from outside.
